Gravity cast aluminum parts have practical applications in multiple industries. The following provides an objective description by industry classification.

In the automotive manufacturing industry, gravity cast aluminum parts are used for chassis and powertrain components. Typical applications include: engine intake pipes, throttle bodies, water pump housings, brake calipers, wheel hubs, and connecting brackets in suspension systems. These components typically require good airtightness, certain mechanical properties, and dimensional stability, which can be met by gravity casting with controllable individual cost.

In the field of general machinery and power tools, gravity cast aluminum parts are used in small gasoline engine cylinder heads, crankcase housings, chainsaw housings, lawn mower chassis, air compressor valve plates, etc. These components have complex shapes and need to withstand thermal cycling or vibration loads. Gravity cast aluminum parts are adapted to different working conditions by adjusting the alloy grade and heat treatment state.

In electrical and communication equipment, gravity cast aluminum parts are used to manufacture heat sinks and shielding shells. The high thermal conductivity of aluminum alloy combined with the dense structure formed by gravity casting can effectively conduct heat. The heat dissipation bottom plate of some high-power power modules is also formed by gravity casting technology.

In the field of hydraulic and pneumatic components, gravity cast aluminum parts are used for components such as valve bodies, pump bodies, and joints that withstand medium pressure. Due to the fact that gravity cast aluminum parts can be strengthened through heat treatment and have good internal density, they can meet the requirements of pressure resistance testing. In addition, application examples of gravity cast aluminum parts can also be found in industries such as rail transit, medical equipment, and instrumentation.
